Reflexes WK5 L3 Flashcards
WHAT IS A REFLEX?
A FAST INVOLANTRY MOVEMENT COMPLETED BY LOWERE MOTOR NEURONS
WHAT ARE REFLEXES INVOLVING THE SKELETAL SYSTEM?
SOMATIC REFLEXES
WHAT ARE REFLEXES INVOLVING THE CARDIAC OR SMOOTH MUSCLES & GLANDS?
AUTONOMIC/VISCERAL REFLEXES
WHAT ARE THE MAIN TYPES OF REFLEXES?
WITHDRAWL REFLEXES (REMOVAL FROM DANGER BODY POSITION (ENSURING MUSCLES ARE CORRECT LENGTH)
WHAT ARE SKELETAL MUSCLES COMPOSED OF?
INDIVIDUAL MUSCLE FIBRES THAT CONTRACT WHEN STIMULATED BY A MOTOR NEURON
(EXTRAFUSAL FIBRES)
WHAT ARE INTRAFUSAL FIBRES?
FORM THE MUSCLE SPINDLE APPARATUS - DETECT THE AMOUNT OF CHANGE AND RATE OF A MUSCLE
(FOUND BETWEEN EXTRAFUSAL FIBRES)
WHAT IS A MONOSYNAPIC REFLEX?
A REFLEX THAT HAS ONLY ONE SYNAPSE BETWEEN SENSORY NEURON AND MOTOR NEURON
WHAT IS RECIPRICOL INHIBITION?
THE RELAXATION OF MUSCLES ON ONE SIDE TO ACCOMMODATE FOR RELAXATION ON THE OTHER SIDE
WHAT DOES RECIPRICOL INHIBITION PREVENT?
MUSCLES FROM WORKING AGAINST EACH OTHER
WHAT ARE THE AGONIST MUSCLES?
MUSCLES THAT WORK TOGETHER TO PERFORM THE OPPOSITE ACTION OF THE OPPOSITE MUSCLE TO WORK WITH IT
WHAT ARE THE ANTAGONIST MUSCLES?
MUSCLES THE APPOSE THE ACTION OF THE OPPOSITE MUSCLE TO WORK AGAINST IT
WHAT IS THE GOLGI TENDON REFLEX?
TENDON RECEPTOR THAT MONITORS THE STRETCH OF MUSCLES
WHAT DOES THE GOLGI TENDON REFLEX DO?
PREVENTS EXCESSIVE MUSCLE CONTRACTION - RELEAXES THE MUSCLES IF THE MUSCLE IS STRETCHED INCORRECTLY OR COULD TEAR
WHAT IS A DISYNAPTIC REFLEX?
A REFLEX THAT HAS TWO SYNAPSES
WHAT IS FLXION?
SMALL ANGLE IN A JOINT GETS SMALLER AS YOU FLEX - PULLING TOWARDS
